TITLE

plural EMC VNX Product SMB Vulnerability in arbitrary code execution in service

Trust: 0.8

sources: JVNDB: JVNDB-2016-004864

DESCRIPTION

The SMB service in EMC VNXe (VNXe3200 Operating Environment prior to 3.1.5.8711957 and VNXe3100/3150/3300 Operating Environment prior to 2.4.4.22638), VNX1 File OE before 7.1.80.3, VNX2 File OE before 8.1.9.155, and Celerra (all supported versions) does not prevent duplicate NTLM challenge-response nonces, which makes it easier for remote attackers to execute arbitrary code, or read or write to files, via a series of authentication requests, a related issue to CVE-2010-0231. Multiple EMC Products are prone to an authentication-bypass vulnerability. An attacker can exploit this issue to bypass authentication mechanism and perform unauthorized actions. This may lead to further attacks. EMC VNX2 File OE and others are all hybrid storage platforms of EMC. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ESA-2016-096: EMC Celerra, VNX1, VNX2 and VNXe SMB NTLM Authentication Weak Nonce Vulnerability EMC Identifier: ESA-2016-096 CVE Identifier: CVE-2016-0917 Severity Rating: CVSS v3 Base Score: 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) Affected products: EMC Software: EMC VNX2 File OE versions prior to 8.1.9.155 EMC Software: EMC VNX1 File OE versions prior to 7.1.80.3 EMC Software: EMC VNXe (all supported versions) EMC Software: EMC Celerra (all supported versions)Note: EMC Unity (all versions) is not affected by this issue. Summary: SMB implementation in EMC Celerra, VNX1, VNX2 and VNXe are affected by an NTLM authentication weak nonce vulnerability that could potentially be exploited by malicious users to compromise the affected system. Details: An unauthenticated remote attacker may potentially exploit the NTLM challenge-response authentication protocol causing the server to generate duplicate challenges/nonces to potentially access the SMB service of the target system under the credentials of an authorized user. This issue is similar to the Microsoft Windows SMB implementation issue that is described under CVE-2010-0231 (https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2010-0231). Resolution: The following releases contain resolutions for this issue: - - EMC VNX2 File OE versions 8.1.9.155 - - EMC VNX1 File OE versions 7.1.80.3 EMC recommends all customers upgrade at the earliest opportunity. This advisory will be updated when fixes for EMC VNXe will be available. There is currently no plan to release fixes for EMC Celerra based on the current support lifecycle of the product. Workaround: Customers that are unable to upgrade should use Kerberos authentication instead of NTLM. Link to remedies: Registered EMC Support customers can download EMC VNX2 and VNX1 software from the EMC Online Support web site at https://support.emc.com.
